Climate change mitigation requires globally, at national levels and locally, and across a range of policy areas. Priorities include widening the scope of carbon markets and investing more in innovative technologies. Efforts to cut emissions need to be stepped up, both in energy-related areas and in sectors like industry, agriculture and waste.

OECD urges efforts to better price carbon as new analysis finds that 90% of CO2-emissions are priced below EUR 30 per tonne, a low-end estimate of climate damage, and 60% are not priced at all. Effective Carbon Rates in the OECD and Selected Partner Economies calculates effective carbon rates (ECR) on CO2-emissions from energy use for 41 countries which together use 80% of global emissions.

Countries everywhere have committed to fighting climate change but many are still subsidising fossil fuels, investing little in green technologies, failing to put a realistic price on carbon, and allowing transport emissions to grow. Much more can and should be done.

In order to help address climate finance-related information needs under the UNFCCC, this paper explores the extent to which currently-available secondary data make it possible to estimate private finance mobilised by developed countries for climate action in developing countries.

Given the years of preparation – and for some OECD colleagues, a life’s work – my hope was for an enduring, ambitious text, helping us to avoid climate catastrophe. My expectation was far less grand, more closely aligned to the reality of getting 195 countries to adopt an agreement with legal force.

A stern warning for climate change, and our health - Shipping brings us 90% of world trade and has increased in size by 400% in the last 45 years. Cargo ships, tankers and dry-bulk tankers are an essential element of a globalised world economy, but they are thirsty titans and they won’t settle for diet drinks. There are up to 100,000 working vessels on the ocean and some travel an incredible 2/3 of the distance to the moon in one year.

China was among the near-200 countries to adopt the Paris Climate Change Agreement (Paris Agreement) at an historic UN conference in Paris, France on 12 December 2015. As an emerging economy and one of the world’s major emitters of greenhouse gases, how China implements the Paris Agreement will be important. We asked Dr Xuedu Lu of the Asian Development Bank for his views.

The Paris Agreement is a landmark in collective efforts on climate change and is the result of many years’ hard work. It must now be implemented.

This paper reviews the latest climate projections for West Africa and considers alternative ways in which the knowledge generated from climate science can be understood in the context of preparing for an uncertain future that provides practical help for decision makers.

Climate change is not just about a change in climate towards hotter, wetter, and drier conditions, but also about an increase in the variability of the climate, as well as in the number and severity of extreme events.

This brief is a contribution to the 22nd Conference of the Parties to the United Nations Framework Convention on Climate Change (COP22) and a submission of recommendations for the renewal of the Lima Work Programme on Gender. It provides an overview of how well members of the OECD Development Assistance Committee (DAC) are integrating gender equality into their bilateral aid to climate change.

Developing countries are disproportionately affected by the rising trend of losses from climate-related extreme events. This paper uses case studies of Colombia and Senegal to examine how countries are using financial protection as part of their approaches to managing climate risks; it also identifies emerging priorities for development co-operation providers in supporting financial protection against climate risks.

This report provides an analysis of how climate change damages may affect international trade in the coming decades and how international trade can help limit the costs of climate change. It analyses the impacts of climate change on trade considering both direct effects on infrastructure and transport routes and the indirect economic impacts resulting from changes in endowments and production.

Integrating measures to tackle climate change into regular economic policy will have a positive impact on economic growth over the medium and long term, according to a new OECD report prepared in the context of the German Presidency of the G20.

This report examines the implications of regional climate governance for international trade and conversely the implications of regional trade governance for climate change action. Regional approaches to climate change governance are discussed with a specific focus on the rise of “climate clubs” and their implications for international trade.

Climate change is a clear and undeniable challenge that requires a global response. The Paris Agreement represents the careful crafting of a collective effort of over 190 countries to meet this challenge.

Countries need to look beyond narrow national policy agendas to curb global emissions and reduce climate risks, OECD Secretary-General Angel Gurría said today. Governments should seize the flexibility built into the 2015 Paris Agreement to increase and accelerate their emissions-cutting ambitions.

“National governments must take the lead and do so with a recognition that they are part of a global effort.” Speaking last week at the Munk School of Global Affairs in Toronto, OECD Secretary-General Angel Gurría urged countries not to retreat behind their national borders in dealing with climate change.

Infrastructure resilience requires a coordinated policy response to ensure that infrastructure owners and developers have the incentive and capacity to integrate resilience. The framework is aimed at policy makers in OECD countries, but the underlying messages can be applied to other country contexts.

Ending poverty and combating climate change: two years after the adoption of the UN Sustainable Development Goals and the Paris Climate Agreement, these inter-related challenges remain as daunting as ever, not least in developing countries.

Our response to the climate challenge will define our collective future for generations to come. We must act. We must act swiftly, collectively, and decisively.

On the occasion of the One Planet Summit, read our latest OECD Observer articles focusing on the challenges and opportunities for climate action, particularly in the area of green finance and investment.

Taxes are effective at cutting harmful emissions from energy use, but governments could make better use of them. Greater reliance on energy taxation is needed to strengthen efforts to tackle the principal source of both greenhouse gas emissions and air pollution, according to a new OECD report.

12 September 2018, San Francisco - Cities and regions are critical financial actors in the global response to climate change, and particularly in the infrastructure. This expert panel will discuss how national and sub-national governments, as well as private actors, can scale up subnational financial flows to transition to low-carbon, resilient and inclusive cities, presenting the findings from OECD and World Bank studies.

Governments need to raise carbon prices much faster if they are to meet their commitments on cutting emissions and slowing the pace of climate change under the Paris Agreement, according to a new OECD report.

On 25 September 2018 in New York, the OECD, UN Environment and the World Bank Group hosted a high-level panel discussion on their joint initiative “Financing Climate Futures: Rethinking Infrastructure”. The project is being undertaken with the support of the German Federal Ministry of the Environment, Nature Conservation and Nuclear Safety.

Three years on from the commitments made at COP21 in Paris, the overwhelming majority of governments have not taken the necessary action to contain growing risks to the climate. With emissions on the rise again, OECD governments need to get serious about shifting their economies to a low-carbon model and stop investing in carbon-intensive infrastructure.

This paper explores the consequences on the labour markets of structural changes induced by decarbonisation policies. These policies are likely going to have consequences on labour-income distribution given i) existing rigidities in the labour markets, and ii) their different impacts on sectors and on job categories.

This report investigates the effects of select climate policies, non-climate policies, as well as political economy factors on the decarbonisation of electricity in OECD countries from 2000 to 2015. Effects are analysed on the three phases of decarbonisation: (1) increasing the share of renewables installed, (2) increasing the use of renewables in generation, and (3) reducing the emissions from electricity.

The OECD, UN Environment and World Bank Group today called on leaders of G20 countries to do more to enable a radical shift of investment into low-carbon, climate-resilient infrastructure as a way to limit the impact of climate change.

Public climate finance from developed to developing countries totalled USD 56.7 billion in 2017, up 17% from USD 48.5 billion in 2016, according to new data compiled by the OECD.

2-15 December 2018, Katowice, Poland - The key objective of this year’s event was to finalise the "Paris Rulebook". Find out about the full OECD participation through a series of side events, publications, and by taking part in a number of workshops, seminars and other events throughout the conference.

A co-ordinated policy response is needed to ensure that new and existing infrastructure networks are resilient to climate change. This Policy Paper outlines a framework for achieving this based on the experiences in OECD and G20 countries. It shows how governments and businesses can collaborate to mobilise investment for climate-resilient infrastructure.

This event focused on the implication of COP24 outcomes and the implementation of the Rulebook, as well as on upcoming work on unresolved issues such as Article 6. Discussions covered Common Tabular Format (CTF) for climate finance and tracking progress towards the mitigation targets and updating and implementing NDCs, with a particular attention to the power sector and carbon markets.

Fossil-fuel subsidies are environmentally harmful, costly, and distortive. After a 3 years downward trend between 2013 and 2016, government support for fossil fuel production and use has risen again, in a threat to efforts to curb greenhouse gas emissions and air pollution, and the transition to cleaner and cheaper energy.

On 3rd July 2019, in his fourth biennial climate change lecture, OECD Secretary-General, Angel Gurría focused on how countries can overcome the numerous political, economic and social barriers to achieve the rapid reductions in greenhouse gas emissions needed to safeguard our common future. Follow this link to watch the full lecture and the press release.

OECD Secretary-General Angel Gurría today said governments must face up to mounting anger, particularly among youth, on climate inaction.

Climate change and outdoor air pollution are two of the most challenging environmental issues that modern society faces. This paper presents the first global analysis of the joint economic consequences of climate change and outdoor air pollution to 2060, in the absence of new policies to address these challenges.

Climate finance provided and mobilised by developed countries for climate action in developing countries reached USD 71.2 billion in 2017, up from USD 58.6 billion in 2016, according to new estimates from the OECD.

This paper focuses on how national and sub-national governments can align subnational financial flows to transition towards low-carbon, resilient and inclusive cities. The paper is a contribution from the OECD Champion Mayors for Inclusive Growth initiative and to the OECD Programme on Subnational Finance and Investment.

National development banks (NDBs) and development finance institutions are poised to play a role in bridging the investment gap for climate-compatible infrastructure in developing countries. This paper highlights the role of NDBs drawing from case studies of the Brazilian Banco Nacional de Desenvolvimento Econômico e Social and the Development Bank of Southern Africa.

Developing countries are at the forefront of the ongoing battle to address climate change. Roughly 60% of the new infrastructure built before 2030 will be in the developing world, and it is these investment decisions that will determine our collective ability to address the climate emergency.

Donor countries must do more to bring development finance in line with climate goals, raising the share used for climate action and reducing to zero the amount that supports new fossil fuel activities, according to a new OECD report.

The OECD will be actively contributing to this important event through a series of side events, publications, and by taking part in a number of workshops, seminars and other events throughout the conference. Find out about the full details of OECD schedule of events.

Organised in collaboration with PLACARD, the European research platform on Climate Change Adaptation and Disaster Risk Reduction, this conference will bring together climate change adaptation and wildfire experts from governments and public agencies to discuss recent insights into wildfire risks as well as the extent to which policies have been able to address emerging challenges.

The European Union may be facing some difficult economic challenges, but that's no excuse for not acting now to create an economy based on resource efficiency and low-carbon development. The benefits are potentially enormous, including lower greenhouse gas emissions, more efficient use of energy and resources and rising growth and innovation.

Health is both a precondition for, and an outcome of, sustainable development. Climate change affects health through a myriad of exposure pathways, each presenting simultaneously both challenges and opportunities for sustainable health and development.

Credible and consistent carbon pricing must be the cornerstone of government actions to tackle climate change, according to a new OECD report.
